Abstract
A transflective liquid crystal display device includes: first and second substrates facing and spaced apart from each other; a gate line on an inner surface of the first substrate; a data line crossing the gate line to define a pixel region including a reflective portion and a transmissive portion, wherein the transmissive portion has a polygonal shape inscribed in a rectangle, and a circumference of the transmissive portion is less than the circumference of the rectangle; a thin film transistor connected to the gate line and the data line; a passivation layer on the thin film transistor, the passivation layer having a opening corresponding to the transmissive portion; a reflective layer corresponding to the reflective portion on the passivation layer; a transparent electrode corresponding to the pixel region over the reflective layer; a color filter layer on an inner surface of the second substrate; a common electrode on the color filter layer; and a liquid crystal layer between the common electrode and the transparent electrode.
